London, England Application August 29, 1936, Serial No. 98,520 In GreatBritain January 3, 1935 2 Claims.

This invention relates to improvements in registering apparatus forincorporation in totalizator and like equipment, of the type adapted toreceive bet signal impulses directly or indirectly from ticket-issuingand like machines and including stepwise-operated primary mechanism.

The present invention provides improved apparatus of the type referredto including a series of register discs each of which, after the firstor units register disc, is driven from the preceding register disc bymeans including a cam driven step wise by the preceding register discoperating mechanism and operatively connected to a toothed Wheel of thesucceeding register disc operating mechanism whereby to impart a step ofrotation to said toothed wheel in the final step of rotation of saidcam.

Registering apparatus constructed in accordance with the presentinvention is illustrated in the accompanying drawings in which Fig. l isa rear elevation, Fig. 2 a part plan part horizontal section and Fig. 3a fragmentary elevation drawn to a larger scale of the transfermechanism which interconnects one register disc with a succeeding s--register disc.

The registering apparatus shown includes an electro-magnet I (Fig. 1)which receives electrical bet-representing impulses to be counted andwhich imparts oscillatory movements to an armature lever 2 attraction ofwhich to the electro-magnet I is opposed by a pair of springs such asindicated at 6. The armature lever 2 carries a pawl 4 adapted, in thereturn vibrations of the armature lever Zunder the action of the springs6, to impart stepwise uni-directional rotation to a ratchet wheel 5,reverse rotation of which is prevented by a detent 5'. The ratchet wheel5 transmits rotation to a spur wheel 9 through accumulator mechanismforming the subject of my co-pending application Serial Number 98,519,filed August 29, 1936.

Each impulse transmitted by the spur wheel 9 to a rotarydigit-displaying disc I! geared thereto counts unity, digits 1-9 and 0beingequispaced circularly on the front face of the disc I! which isrotated through one-tenth of a revolution for each transmitted impulse,so as to exhibit a digit. The digit disc [1 and its associated drivingmechanism constitutes a first or single units indicating apparatus.

A digit is exhibited by the disc ll when said digit registers with awindow in a front panel (not shown) of the apparatus.

The first or single units register disc may be actuated by two suchdriving mechanisms as described, the spur wheels 9 of said mechanismsmeshing with pinions l2, l2 respectively, (Fig. 2).

These pinions rotate freely on the fixed shaft 3. Integral with thepinion l2 and rotating about the same shaft 3 is a bevel gear 1 whichforms part of the differential gearing [3. The other parts of thedifferential gearing are the bevel gears 8, l9 and II. Gear 8 isintegral with pinion l2 and rotates with it about the shaft 3. The gearsI0 and H are mounted on a disc 33 which is joined to the gear wheel iiand rotates with it about the shaft 34 which joins the pinion I2 to thebevel gear 8. Locknuts 35 and 3% keep the Various gears in their properspatial relationship. It will thus be seen that impulses received by thepinions l2 and li will be transmitted independently of one another tothe gear wheel M. For example an impulse received by pinion l2 will betransmitted to the gear I and cause the conjoint rotation of pinion i2and gear 7. Rotation of the gear I will cause rotation of gears l0 and Hwhich will roll over the surface of gear 8 without causing it to rotate.The rolling of gears Ill and H on the surface of gear 8 will rotate disc33 and impart an equal amount of rotation to the interconnected gear l4.Rotation of the pinion l2 will produce identical results but in thiscase the gears l5 and l I roll over the gear 1 without causing it torotate.

Rotation of the gear wheel It will rotate the gear wheel [5 with whichit meshes. The gear wheel i5 is integral with the shaft 3'! which isfree to rotate on the spindle l5. Integral with one end of the shaft 3'!is a dog-clutch element i it which cooperates and meshes with a matingdog-clutch element 1 l2 which is provided with a rectangular groove, andwhich is slidably mounted on shaft IS. A tongue 38 which is rigidlyfixed to the shaft I6 is partially inserted in this groove and serves totransmit rotary motion directly from the clutch element H2 to the shaft!6. Likewise, rotary motion received by the gear wheel IE will betransmitted directly to the shaft l6 by means of the intermeshed clutchelements H2 and H3. The dog-clutch elements may be disengaged by movingthe element H2 away from the element I I3 and thereby causing the tongue33 to be projected more deeply into the groove in the element H2. Whenthe clutch members are completely disengaged the spindle it will be freeto rotate without being checked by the mechanism which actuates gear l5and normally prevents the spindle from rotating independently.

In order to disengage the clutch members the register is provided with arotatable shaft 39 which is situated below and at right angles to thespindle [6. The shaft is provided at one end with a weighted lever 82which is rigidly attached to the shaft. Lifting of the lever 82 willcause rotation of the shaft 39. Rigidly attached to the shaft 39 are anumber of flat plates 69 on each of which is mounted a pair of spacedpegs 4|. The lip 42 on the clutch member l I2 extends into this spacebetween the pegs. The pegs are also ment with the toothed wheel 22 iscontrolled by so situated on the plates 0 that rotation of the shaft 39by lifting the lever 82 will cause the pegs to move toward the axisofthe shaft -39. As the pegs move toward this axis they will carry withthem the lip 42 and will ultimately cause the clutch 'member 2 to bewithdrawn completely from the clutch member I I3.. Reversal of therotation of the shaft 39 will of course cause the clutch members to bere-engaged.

The spindle I6 is provided at one end with a digit disc I! whichisrotated one-tenth of a revolution for each impulse received.

On'its end remote from the digit'disc. l! the.

spindle l6 carries a snail cam |8 (Fig. 3) engaged by a follower I01 ona lever |9 urged by a spring 20 in the direction to keep the followerI01 in" engagement with the cam |8. The lever I9 is pivoted between itsends at I08 and has pivoted on its end remote from the follower ID! alink I09 presenting a pin 2| adapted to impart stepwise rotation to atoothed wheel 22 which is freely rotatable on shaft 'IB but which isselectively connected through clutch H2, H3 with shaft I 6 to drive aregister disc ||ll similar to and partially overlapping the units digitdisc IT. The movement of the pin 2| into and out of engageareciprocatory guide link 24- one end of'which presents an arcuate guideslot 23 in which works the pin 2|.

is connected by the pin 25 to one arm of a U-shaped member I whichoscillates about the shaft 43. The other arm of the member H! isconnected by the link 26 to pin 21 which is mount- ;ed on the snail cam8. Consequently rotation of the cam I8 will cause 'reciprocatory motionof the guide link 24. As viewed in Fig. 3, the cam l8rotatescounter-clockwise. As the follower rises under the action of thecam IB-the-spring 20 is stretched and the pin 2| is constrained, un-

der the combined control of the cam l8 and the a guide link 24, tovacate an interdental space and to enter a succeeding interdental spaceof the toothed wheel 22. When the peakof the cam I8 .,passes beyond thefollower I01 the follower dropsinto the root l8 of the cam under theaction of the spring 20 on the lever l9, which latter is thus forciblyrocked and imparts'a step of rotation equal to one-tenth of a revolutionto the toothed wheel 22 through the medium of the link I09 and the pin2|. A pair of detent pins 30 onthe guide link 24 co-operate with thetoothed wheel 22 in order positively to lock the latter during the intervals between successive steps of rotation of the toothed wheel 22; Aswill be understood from an examination of Figure 3, with cami|8 beingdriven by shaft I6 in a counterclockwise direc-' tion, pins 30 will bemoved about a tooth of wheel 22, and pin 2| operating in guide slot 23will .not engage wheel 22. Pins 30 will be movedto the right as viewedin Figure 3 until the pin 21 on cam l8 reaches a position in. a linehorizontal with the shaft l6. 7 Continued rotation of cam l8 in acounterclockwise direction will cause pins- 30 to move to the left andthis movement will continue until the pin 21 on cam |8 assumes'apositionat the left of shaft I6" and in alposition substantially horizontal withrespect to shaft I6. During this movement pins. 30 will be movedcompletely, free of wheel 22 and pin 2| will be moved into a positionbetween two teeth of wheel 22. At the time when pin'21- is in ahorizontal position with respect to shaft and to the left thereof,follower andv cam |8 arein such a position that follower may beoperatedby. a.

The other end of the guide link 24 spring 20, to assume the Zeroposition with the follower ID! in the root |8 of the cam, as thefollower moves over the peak point of cam" I8, to thus cause pin 2| torotate wheel 22 as desired; Upon further rotation of cam I8; the pin21'will now be moved toward the right, pin 2| will be moved out ofengagement with wheel 22 and pins 30 will consequently be moved to aposition to engage wheel 22'to thus hold wheel 22 in its new posi- ,tionuntil the above cycle is repeated. 32 denotes a guard'plate secured onthe shaft I6 and adapted to guard or shield the projecting end of thefrollower'pintl as the follower I0! drops over the peak and into theroot of the cam |8. 'When the cam I8 is in the angular setting in whichits root depression |8 is engaged by the follower I01 the Zero digit isexhibitedby the disc The pin 21 carries a roller 28 which co-operates inthe rotation of the pin with a circular group of electric contacts 29(Fig. 2) adapted tocontrol a large remotely disposed public indicator,

Mechanism similar tothe transfer mechanism connecting the shaft l6 ofthe units register disc with the shaft I6 of the tens register disc is.

interposed between the shaft l6 and the shaft H5 of a hundreds registerdisc, and is repeated for each subsequent register disc required.

All of the register discs are zeroized simultaneouslyby raising aweighted master lever 82,.

snail cams |8 rotates said cams with their shafts and .digit discs in aclockwise direction until the cams come to rest with their rootdepressions I8 engaged by the associated followers ID! on the levers I9,in which angular settings of the cams the digit discs exhibit their zerodigits. During the. zerosetting movement of anyone group of parts. l9,2|, 24, etc, the associated wheel 22 of the succeeding register disc isheld by pins 30 but this has no effect upon the register disc associatedwith the wheel 22 due to the declutched position of the clutch H2 and 3.f

I claim:

1. A mechanism for transferring stepwise impulses from a register discof lower order to one of higher order, which comprises a cam rotated bysaid register disc of lower order,. a toothed wheel capable of rotatingsaid register disc of' a.

higher order, a spring-pressed lever actuated by saidcam and linked toapinengageable with the toothed wheel, areciprocating guide link, saidpin being also under the control of said reciprocatingguide link, meansfor actuating said reciprocating guide link concurrently with the cam,

the conjoint effect of the spring-pressed lever V and the reciprocatingguide link being such as to impart a stepwise rotation to said toothedwheel to rotate the register disc of higher order when the register discof lower order has been rotated a predetermined amount. a

2; A mechanism as claimed in claim 1 in whic the reciprocating guidelink carries detent means for preventing the rotation of the toothedwheel during the intervals between the successive steps of rotation ofsaid toothed wheel.
